Preparation of rare earth doped laser materials
Abstract
This report describes the preparation of both polycrystalline and single crystal host materials which may prove to be suitable for new lasers. Three classes of hosts were examined along with specified lanthanide dopants. The latter were most frequently the elements Ce, Pr, Er, and Yb. Single crystals of YAG were grown by the Czochralski method in production pullers. Dopants were added under controlled atmospheric conditions. Various fabricated optics such as polished rods, disks, or rectangular parallel pipeds were constructed for active laser testing. A significant study was made on high melting oxidic hosts with a fluorite crystal structure.
